An interesting and worthwhile interview (available on YouTube) with security researcher Amit Serper reveals a lot more detail about the Autodiscover credential leak reported by Guardicore last month. The interview (with three Office 365 MVPs) goes through the collection of leaked credentials, how Serper tried to reproduce the problem, and his interaction with Microsoft. It’s a real pity Serper didn’t include the information in his original report as it would have taken a lot of heat out of the situation.
